To all whom it 'may concern: U

Be it known that I, FRED R. REED, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vehicle- Lamps, of which the followin is a specification, reference being had t erein to the accompanying drawings.

The invention relates to vehicle lamps of the type ein loyed as headlights, and it is the obJect o the invention to obtain a construction for projecting a powerful light so as to illuminate the road and at the same time to limit the angle of the intense light rays to approximately a horizontal line. It is a further object to obtain a construction which is applicable to lamps of standard lines and which also provides for a moderate illumination of greater angle.

In the drawings:

Figure 1 is a perspective view, showing the forward portion of a motor vehicle with my improved lamp applied thereto;

Fig. 2 is a diagrammatic vertical central section through the lamp;

Fig. 3 is a front elevation thereof.

In the present state of the art the standard construction of lamp is one having a casing of parabolic form, containing a reector of similar form with the lamp arranged at the focal point. It is also common to provide such lamps with an auxiliary light of lesser power and arran ed at a point out of focus. The focused lig t when used is projected through an angle which not only illuminates the road but forms an objectionable glare above the lam level; while, on the other hand, the auxiliary lamp is too feeble to produce satisfactory road illumination. With the present invention I have arranged within a lamp casing of standard lines, a reiiecting shield which throws a concentrated light upon the road but limits the angle to the horizontal. I have also arranged this shield so as not to interfere with the auxiliary light or to limit the angle of the raysv therefrom.

In detail, A is the parabolic casing of the lamp, which may re resent the inner lining or reflector of stan ard construction. ,B is the lamp proper, which is arranged at the .focal point of said casing, and C is the auxiliary lam which as shown is arranged in the upper lcrward portion of the casing.

D is the line representing the plane of the glass front. E is a conical reiiector within the casing A, having its axis substantially coincident with the casing A and having its wall inclined at substantially' a 45 angle to said axis. F is a reliector arranged at an upward angle of less than 45, preferably approximately 225 from the horizontal and of a concave form. G is a combined shield and counter-reflector arranged at an angle preferably of substantially 45, and having its forward edge in the plane of the front D and the horizontal plane of the lamp B.

The rear edge of thls reflector intersects immediately in a vance of the vehicle and at the same time light is pro'ected forwardly below the horizontal plane or a considerable distance. This gives the desired illumination and without any objectionable glare.

What I claim as my invention is:

1. Avreflector for a vehicle lamp having a parabolic casing and a lamp located suhstantially at the focus of said casing, said reflector being insertible within said casing. and comprising a lower portion extending from the margin of the casing to a position in rear of the lamp, an u per ortion connecting with the upper e ge o said lower portion and forming an acute angle with the orizontal, and a inversely-inclined portion connecting with the forward and upper edge osaid acute angle portion, said reverselyr inclined portion being in front of said acute angle portion and having its lower edge in substantially the horizontal plane of the lam A ZPA' reector for a vehicle lamp. having a parabolic casing, a transparent face for said casing and a lamp located substantially at the focus of said casing, said reflector being insertible within said casing and having a continuous redecting surface, comprising a gig;

lower portion at substantially 5 to the horizontal and extending a'om the margin of the casing 1to a osition in near of the lamp, an nppei portion at an angle of sobstanialljy 22 to the horizontal and a neversely-inclined portion in fnont of saiol upper portion and aaving its lowei' erige in subsantially the lnoi'izontal plane of folio lamp and adjacent no the manana-nenn face foi" lle casing ancona? 3. A i'oectoz for a vehicle lamp, conlprising a conical lower portion and an upper portion having front and rear membeis intersecting at an upward inclination, the lower edge of the front member being snlostantially in alle horizontal plane of the anis of alle conical member.

in testimony wheieo" am my signafmne,

REED.
